  1. Salt can not be evaporated. You can do this little experiment where you take a small bowl of water, put salt in it and let it sit in the sun. Then come back to see whats left behind!


  2. the dissolved salts and sediments are aqueous/ solid, they don't evaporate, only the water. the vapour condenses into clouds which as rain.

    you can test this by making saltwater and leaving it out for a day near the radiator. amazingly, the salt is left =P

  3. Because only the water can evaporate off, leaving the salt and whatever else it was mixed with in the sea behind,

    Then it falls as fresh rain water :)

  4. Evaporation of water from sea surface,condensation of this evaporated water (ie water vapour) to form clouds and then precipitation from the clouds form part of the nature's distillation process to produce fresh water.In this distillation process,salt and other impurites of water are left behind.You may be knowing distillation process is used in the laboratory to purify  a liquid involving  heating, condensing and collecting.

  5. Because only the water is evaporated, not the salt.

  6. When the water is evaporated, the salt and other sediments in the ocean water is left behind.

  7. When seawater evaporates to form clouds, almost all of the salt stays behind.
